I evaluate AI outputs and create intuitive visual, multimedia, and digital experiences.
PortugalWhat I'm looking for
At Mercor, I evaluate AI-generated text, visual, and creative outputs for accuracy, quality, consistency, and task adherence, providing structured feedback to improve model behaviour.
Previously, at Sensei, I supported clients using retail technology platforms, investigated technical and data issues, performed dataset QA, and collaborated across technical, operational, and client-facing teams. I also delivered customer support at Via Verde and JD Sports Fashion, with a practical, solution-oriented approach to customer experience.
My background in Audiovisual Design and Communication has led me to create audiovisual and institutional content at Centro Hospitalar Universitário Cova da Beira and work independently in graphic design. I enjoy bringing creativity, technology, UI/UX, and problem-solving together to make digital experiences clearer and more engaging.
